However, liver biopsy is prone to sampling error, and it is sometimes a painful and dangerous procedure. The utility of serial liver biopsies to detect disease progression has not been studied, but it is a critical issue for clinical investigators and physicians.Null HypothesisThe average change ...
Tumors can be benign (non-cancerous) or malignant (cancerous). Malignant tumors are dangerous because they invade surrounding tissues and can metastasize (spread) to other body parts, such as bones, liver or lungs. Cancer cells can evade theimmune system, create their own blood supply (angioge...
Liquid biopsies to analyse cell-free DNA, exosomes and CTCs present in the blood can provide information on the tumour in a far less invasive way than a tumour biopsy. Currently, the enumeration of CTCs in a blood sample is used to guide treatment decisions. Although many cancer patients have...
Blood tests and liver biopsies are used with varying success. The results from one test alone are inconclusive, but when looked at together can give a better diagnosis. The most reliable test is done using imaging technology. It is used successfully in humans but is cost prohibitive in birds....
Sound waves are not dangerous, and no radiation is involved. The most serious risk of an ultrasound involves its use for guiding biopsies. For instance, if an abnormality is seen in the liver, a needle can be inserted into the abdomen with ultrasonographic guidance to collect a sample from ...
Infection with hepatitis B virus (HBV) may lead to acute or chronic hepatitis. HBV infections were previously much more frequent but there are still 240 million chronic HBV carriers today and ca. 620,000 die per year from the late sequelae liver cirrhosi
In 2002, a more dangerous coronavirus emerged in the People’s Republic of China. This coronavirus, SARS-CoV-1, spread from horseshoe bats to palm civet cats and into humans. It infected about 8422 people, killing 774, and then “vanished.”10 The nucleotide similarity between SARS-CoV-1 ...

Invasive bacteria are then handled by the resident immune cells and by the recruited phagocytes that recognize the invaders as potentially dangerous and proceed to their elimination. This is, however, associated with inflammation and tissue damage that, if protracted over time, can lead to chronic ...
Epstein also demonstrated reduced p38 MAPK activation and IL-1β, enhanced IL-10 and dose-dependent suppression of MMP-3 in CMF in curcumin-treated mucosal biopsies [38]. Curcumin has been shown to attenuate colitis in the dinitrobenzenesulfonic acid (DNB)-induced murine model of colitis with...
